I'm also having the same issue as Kaylar. During the xp install where it copies files, 5 files, refuse to copy over. ie4uinit.mui iedkcs32.mui ieframe.mui mshta.mui msrating.mui I'm using ryanvm int updatepack = XPSP3_QFE_UpdatePack_1.0.7_20090811 OnePiece_IE8_WinXPSP3_v1.4.0_AddOn_ENU.7z OnePiece_Windows_Media_Player_11_True_AddOn_v1.7.0_ENU.7z And of course lets not forget xptsp. I've used the addon version and the batch.exe version I've also replaced the xptsp.bat file that u posted into the batch.exe with no luck. Currently i've used Onepieces batch addon creator to make a svcpack addon out of the ie8 installer and hotfixes and so far it has passed through into the GUI installer with 13 mins to go. Will update to see if all is well which it may be from the looks of things. Ok this truly sucks, thought all was well until xp boots, Had an advanced inf error and ie8 nor wmp11 installed correctly... who do i send my gripes to? Ok gonna try the xptsp gui method, (crosses fingers and toes)
